I’m on the same question rn and I need help.
Answer:
it should be : x²= 15²+8²
x²= 225+64
x²=289
x=√289
x=17
1)12 ÷ 3 = 4.
2) 4×2= 8.
3) 9× 8= 72.
4) 8² = 64
5) 64+ 72 = 136
6) 136 - 7 = 129.
If you just want to simplify the expression you get: 8² + 9(8) - 7
But when you simplify that you get the answer below.
